verl/HybridFlow: A Flexible and Efficient RL Post-Training Framework
Toolkit for linearizing PDFs for LLM datasets/training
RWKV (pronounced RwaKuv) is an RNN with great LLM performance, which can also be directly trained like a GPT transformer (parallelizable). We are at RWKV-7 "Goose". So it's combining the best of RNN and transformer - great performance, linear time, constant space (no kv-cache), fast training, infinite ctx_len, and free sentence embedding.
